That probably means you have some undefined symbol most likely due to
a missing library during link time.

That being said, even if you manage to load and compile the stuff,
wrapping an OpenMP library is *probably* asking for trouble as ruby is
a single threaded application that relies on knowing how and where the
stack is.  OpenMP will generate new threads behind your back, each one
with its own stack.  Any call from those threads back to ruby will
probably lead to random crashes or memory issues.
